基于NI CompactRIO的大型变频鼓风机数据采集和分析系统

Data Acquisition and Analysis System of Large Frequency-converting Blower Based on NI CompactRIO

基于LabVEW开发环境与NI CompactRIO嵌入式平台,开发了大型变频鼓风机数据采集与分析系统。利用NI定点运算、重采样等工具包,实现了24通道数据同步采集、数据实时等角度重采样、阶比分析、多特征值实时计算等功能。系统所涉及的大部分运算都在三百万门的FPGA模块上进行,使系统具有的高运算效率和高可靠性等诸多优势。

A data acquisition and analysis system of large frequency-converting blower based on NI CompactRIO and LabVIEW was developed. This system with functions of 24-channel data acquisition, uniform angle resampling, order analysis and characteristics calculation was implemented by utilizing NI toolkits such as resampling toolkit and fixed-point math library. Most calculation functions involved in the system were deployed in 3M FPGA module makes the system has high-performance and high reliable.
